Mashed Potato Green Bean Casserole is a delicious combination of two of my favorite Thanksgiving sides. On the bottom, a creamy layer of mashed potatoes covered by a cheesy green bean casserole.
Each one tastes incredible on its own, but even better when combined into one extraordinary side.
Best thing about the recipe?
It’s a total breeze to prepare thanks to Simply Potatoes Traditional Mashed Potatoes®.
Simply Potatoes Traditional Mashed Potatoes are made from real ingredients, fresh never frozen potatoes. You can find them in the refrigerated section of your store or learn more about them here.
No time wasted peeling potatoes. These potatoes are ready to be heated and eaten. So much prep time is saved and they are my go-to secret weapon to easily prepare a meal the whole family will enjoy.
I think you’re really going to love the way a layer of Green Bean Casserole (with cheddar cheese no less!) tastes on top of these mashed potatoes. I use fresh green beans, but you can use canned, plus a can of cream of mushroom soup, a little milk and soy sauce, and lots of French fried onions.
Trust me when I say if you’re a fan of green beans casserole and you like mashed potatoes (who doesn’t?) you are going to love this Mashed Potato Green Bean Casserole!
Type Of Green Beans To Use
I use fresh, cooked green beans that I have boiled until tender. You can use canned green beans if you prefer or frozen green beans that have been cooked according to package directions.
Add A Little Spice
To make this recipe spicy, add a pinch or two of cayenne pepper.
Make Ahead and Storage
Can be assembled ahead of time but wait to add the onion topping just before baking. Leftovers will keep in an airtight container in the refrigerator for 3 days. Reheat in a 350 degree oven to crisp the topping back up.

This was a family favorite and so easy to put together.
I boil my potatoes in vegetable broth and water. I also mix in 1 tbsp. Garlic Paste. 1 tbsp. Sugar. 1/4 Cup finely chopped red onion. 1/8th cup shredded white cheddar cheese. A stick of REAL butter. This is for 5 lb. Bag of russett potatoes (10 potatoes total) 1 tbsp salt and 1 tsp black pepper. 1/= cup to 1/2 cup whole milk warm or room temperature. I NEVER use a mixer. Makes potatoes gummy. I use a hand masher and don’t over do it.
I do not add milk. I add both sour cream and cream cheese in its’ place. So good and creamy.
